Method Detail

getActiveSession

Session getActiveSession()

This method returns the current session to the requester. The current session will be the active UnitOfWork within a transaction and will be a 'scrap' UnitOfWork outside of a transaction. The caller is concerned about the results then the getSession() or getUnitOfWork() API should be called.

getServerSession

ServerSession getServerSession()

Return the underlying server session

getUnitOfWork

UnitOfWork getUnitOfWork()

This method will return the transactional UnitOfWork during the transaction and null outside of the transaction.

getSession

Session getSession()

This method will return a Session outside of a transaction and null within a transaction.

createQuery

Query createQuery(Expression expression,
                  java.lang.Class entityClass)

This method is used to create a query using a EclipseLink Expression for the entity class.

createQuery

Query createQuery(DatabaseQuery query)

This method is used to create a query using a EclipseLink DatabaseQuery.

createQuery

Query createQuery(Call call)

This method is used to create a query using a EclipseLink Call.

createQuery

Query createQuery(Call call,
                  java.lang.Class entityClass)

This method is used to create a query using a EclipseLink Call for the entity class.

createQueryByExample

Query createQueryByExample(java.lang.Object exampleObject)

This method is used to create a query using query by example.

createDescriptorNamedQuery

Query createDescriptorNamedQuery(java.lang.String queryName,
                                 java.lang.Class descriptorClass)

This method will create a query object that wraps a EclipseLink Named Query.

createDescriptorNamedQuery

Query createDescriptorNamedQuery(java.lang.String queryName,
                                 java.lang.Class descriptorClass,
                                 java.util.List argumentTypes)

This method will create a query object that wraps a EclipseLink Named Query.

load

void load(java.lang.Object entityOrEntities,
          AttributeGroup group)

This method will load the passed entity or collection of entities using the passed AttributeGroup. In case of collection all members should be either entities of the same type or have a common inheritance hierarchy mapped root class. The AttributeGroup should correspond to the entity type.

copy

java.lang.Object copy(java.lang.Object entityOrEntities,
                      AttributeGroup group)

This method will return copy the passed entity using the passed AttributeGroup. In case of collection all members should be either entities of the same type or have a common inheritance hierarchy mapped root class. The AttributeGroup should correspond to the entity type.
